UNITED STATES PATENT OFFICE.

ERASTUS STEBBINS, OF CHIGOPEE, MASSACHUSETTS.

FAUGET.

Specification of Letters Patent No. 32,797, dated July 9, 1861.

To all whom it may concern:

Be it known that I, E. STEBBINs, of Chicopee, in the county of Hampdenand State of Massachusetts, have invented a new and useful Improvementin Faucets or Cocks; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, in which-Figure l is a vertical central section of my invention taken in the line0c, ai, Fig. 2. Fig. 2 is a horizontal section of the same, taken in theline y, y, Fig. l.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to that class of faucets or cocks in which thevalve is operated by a screw.

The object of the within described invention is to dispense with the useof a spring and open and close the valve by a screw alone, and at thesame time have the packing of the cap attached to the screw shaft orstem, so as to admit of the perfect working of the valve whileeffectually preventing the escape of water around the cap, and alsoaroundv the screw shaft.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents the tube of the faucetor cock, and B is a partition in thetube, which partition is provided with an opening a, over which a valveC, works. This valve C is at the lower end of a square which is fittedand works in a corresponding` shaped chamber c, in an upright box orprojection cl, on the tube A. The square Z), prevents the valve fromturning under the act-ion of the screw e, by which the valve is raisedand lowered and consequently opened and closed. Just above the squareZ), there is a cylinder f', and above the cylinder there is a screw g,the latter being rather smaller in diameter than the cylinder f, so asto form a shoulder on which a circular piece of packing h, is placed.This packing may be of india-rubber or other suitable material and itsedge fits between the cap D, and the top of the box or projection d, thecap D, being screwed on the box d, as shown clearly in Fig. l.

On the screw g, there is fitted a collar E, said collar being providedwith an internal screw thread so as to screw on g, and provided with aslot z, in its side and a fianch y', which projects inward at its upperedge. This collar E, secures the packing 71 snugly down on the top ofcylinder f, and also serves as a coupling to connect the lower end of ashaft F, on which the screw c, is formed, to the cylinder f, the lowerend of shaft F, having a recess 7c, made in it circumferentially, inwhich the flanch j, of the collar fits, the slot i, admitting of theinsertion of the lower end of shaft F, in the collar E, the lower end ofshaft F, being allowed to turn freely in the collar.

The screw e, of shaft F, works in a female thread made in the apex ofthe cap D, and by turning shaft F, it will be seen that the valve willbe raised and lowered and consequently opened and closed, and thepacking 7L, will rise and fall at its center sufficiently to allow thevalves to open and close, the packing h, being sufficiently large indiameter to admit of this result. By this arrangement it will be seenthat all springs are avoided, the valve being Operated by a positivemovement both up and down, and the packing it, allowed to yield or giveto conform to the movement of shaft F, and still operating effectuallyto preventany water escaping between the cap D, and the top of theprojection al.

I do not claim separately any of the parts herein described. But

Having thus described my invention what I do claim as new and desire tosecure by Letters Patent, is

The connecting of the valve C, to the screw shaft F, by means of thecollar E, which is screwed on the cylinder f, of the valve C, and isconnected to the lower end of shaft F, by the flanch y', and recess le;when said collar is used in connection with the packing h, secured tocylinder f, and tted between the cap I), and the box or projection d, ofthe tube A, substantially as herein described.
